'run Lum Arthur G. von, Toledo, om Application February 26, 1942,v Serial No. 432,470 A 1o claims. (ci. 24a- 14er 'I'his invention relates to a device for use in knitting lor crocheting for the purpose of maintaining a substantially uniform tension on the yarn or. thread, and an object is to produce a' new and iniproved device-of this character by which 'the yarn or thread passing to the knitting or crocheting' eedles,"is at all times maintained under unifonnftensionfso that the work is more even or uniform throughout.

Other objects and advantages of the invention will hereinafter appear and for purposes of illus- `*tration but notI of limitation', embodiments of of the clamp. The part of the clamp which enthe invention are shown on the accompanying drawingin which Figure 1 is a side elevation 4showing the device attached to a hand; Y

Figure 2 is a top plan view of the device shown in Figure 1:

vFigure 8 is a rear end elevation of thedevice 'shownonFigures6and7. i.

The illustrated embodiment shown on Figarm Il, at the front 'end of winch are integral ears which are bent over to form a guide II. At-

other portions.

ures 1 to 5 comprises a relatively ilat elongate tached in any suitable manner to the under side yof the arm I0 rearwardly of the guide II isa truncated cone I2 '.with the larger end opening finger. 'I'he cone I 2 which may be termed. a

rearwardly to receive a finger preferably the foremimbre, impur as indicated at n, tti-affords certain-degree of adiustability. ARearwardly of the thimble or attaching part I2, the arm inclines slightly upwardly as indicated at Mfand then merges with a portion I5 which is substantially parallel with the portionl to which the thimble I2 is attached. The rear end portion of the arm Ill is folded upon' itself to provide a spring nger I5 which inclines upwardly to the main portion oi.' the arm, the free end of the lnger being bent slightly upwardly as indicated at in cross section at the lower free edge |portion bent inwardly as indicated at 2li', and with a laterally projecting portion 2| on the upper arm gages the flat arm portion 4I5 has a rearwardly extending mouth or arched portion 22 and the yarn passes rst through the rear guide I8, then through the arched mouth 22 and then .between `the ann portion I5 and flat portion of the clamp I9 and nally through the front guide II and down to the knitting needles or crochet hook as the case may be. In the front portion of the clamp I9 is a vsubstantiiailiy v-shaped notch 2Ia which serves to guide the yarn or thread when pulled rearwardly or away from the work and to prevent it fromslipping out of the clamp.

It will be manifestthat as the clamp I9 is slid rearwardly, the tension imposed upon the yarn Y is increasedand on the other hand, movement of .the clampjlstoward the front guide I I decreases the tension imposed upon the yarn. In

this manner, the desired tension is imposed on' the yarn at all times and as a consequence, the work, whether it be'knitting or crocheting, is much more even and uniform throughout thus eliminating the objection of having a certain portion of the work under greater tension than The laterally extending piece 2l enables the yarn to be readily slipped into place and similarly the form of the guides II and I8 are such that the yarn or thread can be slipped into place readily and conveniently. The device is preferably attached to theforeilnger of the right hand andiitting preferably over` ythe first jointof the finger and with the arm portion I0 inclined slightlytoward the thumb. In this position the yarn or thread can be directed straight down to the needles.

In this instance, the lower arm of the clamp I9 isproyided with an upwardly projecting portion 25fto fitin one of a series of detents 24 provided in theunder side of the spring finger I6. Thisenables the clamp to be moved to the desited position and retained in the position of adiustment. .Ils` a consequence, when the desired i tension on the yarn or `thread is obtained, the

-clampv Ilwillremain in the selected position.

d In thejform of the invention shown on Figures 6 to 8, the front guide IIa and truncated cone or thimble `Ilia are similar to that above described.

1 4However-'gin this form, the arm Illa extends rearwardly ofthe thimble, then inclines downwardly land rearwardly as indicated at 25; then inclines upwardly as indicated at 26. The arm is then plained. the yarn bent upon itself to'provide an upper spring nger 21. 'Ihe finger 21 has a flange 2B which embraces a portion of the arm Ilia on one side and on the opposite side there is a laterally projecting portion 29. A cut-out 30 is formed in the arm 21 and a similar archedmouth portion 3| is provided adjacent the cut-out 30 to direct the yarn or thread to tween the forward end of the finger 21 and the arm lila.

Embracing the inclined arm portion 26 and the finger 21 is an adjusting and guiding device 32, the guide portion 33 thereof being formed by bending over a portion of the material into loop form and in such manner that the yarn or thread can be slipped into the .guide conveniently. It will be manifest that by forcing the member 32 toward the thimble part l2a, increased friction will be imposed upon the thread or yarn passing through the arched mouth 3| and movement in the opposite direction gradually reduces the friction imparted to the yarn. As above exis slipped beneath the laterally projecting flange 29 into the desired position,

In both forms of the invention above described. not only is friction impar-ted to the yarn but also the-arched tapered mouth portion and the fiat engagement between the finger and arm flattens or irons out the yarn in better condition for knitting. That is an important reason for having the yarn pass between the two fiat surfaces which are clamped together with the desired amount of pressure.

The device hereinabove described may be made of any suitable material such, for example, as sheet metal, plastics or the like. It is to be understood that although I have described embodiments which are the best forms known to me at the present time, changes in details of construction, arrangement and choice of materials may be effected without departing from the spirit of the invention especially as defined in the appended claims.

What I claim is:

1. Yarn tensioning device comprising a pair of arms, one being movable resiliently toward vthe other, a finger attaching part on one arm, a clamp embracing said arms providing a guide for yarn between the clamp and one of the arms, and meansv for causing said clamp to impose greater or lesser tension on the yarn passing through said yarn guide.
